If by this you mean, did Jesus teach a non-physical kingdom of God, of course I believe that. So do all dispensationalists. I refer you to the really great work by dispensational theologian Alva McClain,
The Greatness of the Kingdom.
First of all, what Jews? Many believed on Jesus--3000 in Acts 2. Others rejected Christ and the Kingdom of God.
Now you see, that is exactly
NOT what I look for. I look for a future physical kingdom, prophesied as the Davidic throne in many places,
in addition to the Kingdom of God. Please get this right, will you?
